Summary: | The properties of the nuclear isoscaling at finite temperature are investigated and the extent to which its parameter α holds information on the symmetry energy is examined. We show that, although finite temperature effects invalidate the analytical formulas that relate the isoscaling parameter α to those of the mass formula, the symmetry energy remains the main ingredient that dictates the behavior of α at finite temperatures, even for very different sources. This conclusion is not obvious as it is not true in the vanishing temperature limit, where analytical formulas are available. Our results also reveal that different statistical ensembles lead to essentially the same conclusions based on the isoscaling analysis, for the temperatures usually assumed in theoretical calculations in the nuclear multifragmentation process. |

The properties of the nuclear isoscaling at finite temperature are investigated and the extent to which its parameter α holds information on the symmetry energy is examined. We show that, although finite temperature effects invalidate the analytical formulas that relate the isoscaling parameter α to those of the mass formula, the symmetry energy remains the main ingredient that dictates the behavior of α at finite temperatures, even for very different sources. This conclusion is not obvious as it is not true in the vanishing temperature limit, where analytical formulas are available. Our results also reveal that different statistical ensembles lead to essentially the same conclusions based on the isoscaling analysis, for the temperatures usually assumed in theoretical calculations in the nuclear multifragmentation process. |
